In necessariis unitas, in dubiis libertas, in omnibus caritas

The Latin phrase in necessariis unitas, in dubiis libertas, in omnibus caritas, meaning "in certain things unity; in doubtful things liberty; in all things charity", is often misattributed to St. Augustine of Hippo, but seems to have been first used in the seventeenth century by a German Lutheran theologian called Rupertus Meldenius[?] in the form "in necesariis unita[s], in non-necessariis liberta[s], in utrisque charita[s], meaning "in certain things, unity; in uncertain things, liberty; and in both, charity". It is widely quoted in defence of theological and religious freedom.
